Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Vibration Absorption & Shock Mitigation: Constructed from high-performance elastomeric material to dampen vibrations and reduce noise in hydraulic systems of heavy machinery.
  • Flexible Shaft Connection: Segmented design enables adaptable fit for varying shaft diameters and movements, ensuring seamless operation in excavators like Caterpillar 314C/312CL series.

Key features

  • 1. Corrosion-Resistant Elastomeric Material Technology

    • With a durable elastomeric material construction, this coupling ensures long-lasting performance in harsh outdoor environments. Unlike traditional rigid materials, its corrosion-resistant design reduces wear and extends lifespan by ~30% in abrasive conditions.*

  • 2. Modular Segmented Design for Flexible Adaptability

    • With a segmented, interlocking structure, the coupling easily adjusts to fit varying shaft diameters and accommodates misalignment. This design offers 2x easier installation compared to rigid couplings, reducing downtime in field repairs.*

  • 3. Vibration-Dampening Performance for Reduced Noise

    • Engineered with vibration-absorbing properties, this coupling minimizes noise transmission by up to 40% in high-torque applications. This outperforms standard metal couplings, which can amplify vibrations in machinery.*

  • 4. OEM-Certified Compatibility for Caterpillar Excavators

    • Designed specifically for Caterpillar 314C/314CCR/312CL/311 models, it meets Caterpillar’s stringent OEM standards for hydraulic pump systems. This ensures seamless integration and reliability compared to generic aftermarket parts.*

  • 5. Durable Construction for Continuous Commercial Use

    • Built to withstand continuous operation in heavy-duty construction scenarios, this coupling maintains structural integrity under extreme pressure. Field tests show it operates 50% longer between replacements than standard plastic couplings.*
